CLAMP FOR SOLDERING EAVES-TROUGHS.

SPECIFICATION forming part of Letters Patent No. 326,372, dated September 15, 1885.

Application filed July :20, 18t5. (No model.)

To all whom it may concern:

Be it known that l, SAMUEL Yarns, a citizen of the United States,residingat Mnscogee, in the Greek Nation, Indian Territory, have invented certain new and useful Improvements in Machines for Manufacturing Eaves-Troughs; and I do hereby declare the following to be a full, clear, and eXact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and fig 11 res of reference marked thereon. which form a part of this specification.

This invention relates to machines for manufacturing eaves-troughs and gutters; and it consists in a certain improvement on a de vice for such purpose for which Letters Patent No. 57,615 were issued to me August 28, 1866.

In the accompanying drawings, Figure l is a perspective view of my improved device. Fig. 2 is an end view of the same. Fig. 3 rep resents a plan view of the same inverted.

A designates a semi cylindrical bar, commonly made ofwood,to which the metalsheets of which the eaves-trough is to be constructed are secured for soldering.- The bar has a pivotal support at both ends in posts B, being pivoted in such a manner that the bar, with its attachments. is balanced with its convex surface u p ward.

0 indicates a plate fastened to the lower surface of bar A at its edge, and to said plate are severally hinged the clamping-bands D, conforming,as shown,to the convex surface of the bar, and having formed at their hinged ends small curves or offsets c, to close about a bead on the edge of the trough. A number of the bands D are placed a suitable distance apart, so as to close over the bar A, Where the edges of the sheets lap one on another to be soldered together, and, as shown in Fig. 3, each of the bands is laterally adjustable at its hinged end to the right or left,

havinga limited movement on a rod. b.

In the bar A or plate 0, or both, are formed recesses E, which permit the hinged ends of the clamps D to move along the rods b. The object of this is to enable the workman to set the clamping-band at either side of the solderingline, according to the direction in which it is intended the water shall run in the trough, the metal sheets lapping one on another, so that the water passes freely over the seams.

To the under side of bar A,0r to plate 0, are secured a number of springs, d, each spring being in position to connect with one of the bands D, and thus form a clamp. Each of said springsis formed of asubstantial r0d,aud 63 has one end secured by a pivotal connection to plate 0, the other end being extended forward to lock with a band D. The spring is firm iniits position when locked with the band, which is held down firmly on the metal sheets 65 placed on the bar, but when unlocked it may be turned to the right or left,according to the relative position of the band, to which it may be locked by pressing its free end into one of the notches e in opposite edges of the band.

In Fig. 3 the change of position of a band D and the movement of spring-rod d are incated in dotted lines at w.

The improvement described is found in practice to add considerably to the utility and 7 convenience of the device. 7

Having described my invention, I claim-v In a clamping device for the manufacture of eaves-troughs, in combination with a semicylindrical bar, A, laterally-movable hinged bands D and pivoted spring-rods d, adjustable to the right or to the left to connect with said bands, substantially as set forth and described.

In testimony whereof I affix my signature in presence of two witnesses.

SAMUEL YATES.
